波尔山羊×宜昌白山羊F_1代杂种羊生产性能的测定

Determination of the Production Performance of F_1 Hybrid Goat of Boer Goat and Yichang White Goat

[目的]提高宜昌白山羊的生产性能。[方法]通过人工授精,利用波尔山羊精液对宜昌白山羊进行改良,研究F1代杂交山羊的生长性能、屠宰性能和板皮性能。[结果]在相同的饲养管理条件下,F1杂种山羊初生重,2、4、8、12月龄体重均明显高于宜昌白山羊,差异极显著(P<0.01)。F1代杂种山羊2、4、8、12月龄体长分别比宜昌白山羊提高32.46%、30.00%、32.05%和26.57%,胸围分别提高26.41%、23.68%、29.39%和19.73%。12月龄F1代杂种山羊的平均胴体重比宜昌白山羊高7.52 kg,屠宰率(47.26%)比宜昌白山羊高6.67个百分点。F1代杂种山羊鲜皮重、板皮面积均比宜昌白山羊显著提高。[结论]利用波尔山羊杂交改良宜昌白山羊的生产性能是可行的,值得推广。

[ Objective ] The aim of the research was to enhance the ＂production perfomance of Yichang white goat. [ Method] Through artificial insemination, Yichang white goat was improved by using the semen of Boer goat. The growth performance, slaughter performance and skin performance of Fl germination hybrid goat were studied. [ Result ] Under the same feeding and management conditions, the birth weight and the body weight of F1 germination hybrid goat on the 2nd, 4th , 8th and 12th month were obviously higher than that of Yichang white goat with extremely significant difference （P 〈0.01）. body length of Fl germination hybrid goat on the 2nd, 4th , 8th and 12th month were increased by 32.46%, 30.00%, 32.05% and 26.57% resp. than that of Yichang white goat, and chest circumference were increased by 26.41 %, 23.68%, 29.39% and 19.73% resp. The average carcass weight of Fl germination hybrid goat on the 12th month was 7.52 kg higher than Yichang white goat and its slaughter rate （47.26%） was 6.67% higher than Yichang white goat. Both the fresh peltry weight and skin area in F1 germination hybrid goat were significantly increased than that of Yichang white goat. [Conclusion] It was feasible to improve the production performance of Yichang white goat by crossbreeding Boer goat.
